Question

In the cafeteria, I saw my sister and her three friends, none of ____ I had ever seen before.

A．them

B．which

C．whom

D．those

Answer 1

C

試題分析：考察定語從句。本題定語從句的先行詞是my sister and her three friends，關(guān)系代詞whom指代先行詞my sister and her three friends作為介詞of的賓語。因?yàn)橄刃性~是人，且作為賓語，故使用whom。AD兩項(xiàng)不能引導(dǎo)定語從句，which的先行詞是物。故C正確。
點(diǎn)評(píng)：定語從句的考查主要就是考查關(guān)系詞的辨析，關(guān)系代詞that, which, whose, whom, as， who在句中做主語，賓語，表語或者定語；where, why, when在句中做狀語。要分析句子成分，看缺少什么成分，就選用相應(yīng)的關(guān)系詞。
